We study the Cauchy‐Riemann operator ∂ ¯ on spaces ℰ γ ( Ω ( θ ) , E ) of smooth functions on an open set Ω ( θ ) ⊂ ℝ 2 with values in a complex Fréchet space E which grow exponentially (γ = 1) on strips rotated by an angle θ. We state sufficient conditions for the surjectivity of ∂ ¯ : ℰ γ ( Ω ( θ ) , E ) → ℰ γ ( Ω ( θ ) , E ) .
